The answer is (4). If you look at a Maxwell-Boltzmann energy curve, you will see that lowering the activation energy will increase the proportion of molecules with sufficient energy for a successful reaction collision. Therefore, a reaction with lower activation energy will proceed more quickly. Often, this lower activation energy is obtained by another mechanistic pathway. Catalysts increase reaction speed through these two basic mechanisms.
Answer: Because acetic acid in solution exists as a mixture of acetic acid & dissociated acetic acid (acetate)
Hope this helps!
C.
Because the amount of energy in the products is less than that of the reactants, the reaction is endothermic. Endothermic reactions use up, or absorb energy.
Because the size and heat
The correct answer is A because a higher population count always results in the use of more resources (and thus less available in the end). This is why carrying capacities of ecosystems tend to get lower as population counts rise.
